SPECIFICATION forming part of Letters Patent No. aalgosdaated April 1 0; 1888. I Application filed May 5I 1887. Serial No. 237,196. (No model.) r

To all whom it may concern;

Be it known that I, DANIEL A. SUTHER- 7 LAND, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have in vented certain Improvements in Sewing-Machine Presser-Feet, of which the following, taken in connection withthe accompanying drawings, is a specification. Referring to the drawings, Figurel is a perspective view representing my improvedpresser-foot and a piece of material, the design being to represent the operation of the foot.

. Fig. 2 is arear elevation of the foot; and Fig.

3 is a plan of thebottomof the foot, Figs; 2

and 3 being on an enlarged scale.

This presser-foot is designed particularly for use in making corrugated seams in boots and shoes and other leather and textile materials,

- which seams have already been patented to of the fin f and are allowed to bear upon the material on either side of the ribs, to the-endme by Letters Patentiof the United States, dated July 30, 1878, No. 206,611." To this end Make an ordinary presser -f oot, A, having needle-hole a and adapted to be attached to the presser-foot bar of an ordinary sewing machine. vided with channel-grooves e e and the intermediatefin, f. Thechannelsareintended toreceive the corrugations' h of the seam, while the finf-is allowed to enter the seam-crease n, 'all' as shown in Fig; 1. The side bars, m, of the foot are extended downward below the bottom that the ribs or corrugations h maybe crowded well up into the grooves e and held therein during the operation of sewing through the material'and stay-pieces Iam aware that presser-feet have been heretofore constructed with a central fin to enter a seam-crease and.

The bottom face of the foot is proguide the material along while beingstayed; o but in the feet heretofore used the central fin' A has been the prominent feature. It is commonly depressed-or projected below the side. barsof the foot to enter and guide the mate rial; but in my foot the sidebars, m, are made the prominent parts and are extendednbelow the central fin, the purpose of the finbeing not to guide the materialbut to simply open,

the seam-crease while being sewed-that is, a 5c while the stay-pieceis being sewed on, 1 g

.It will be understoodthat the corrugations h are formed in the material first and the I foot is d'esigned to hold the oorrugationsin',

shape and'in position relatively to each other" while the operation of sewing on the staystrip t is'being performed.

I am also aware that a presscr-foot has been;

heretofore constructed with a groove adapted to receive a welt, and with a recess formed in I the'under surface of 'said foot to allow the passage of several thicknesses of material which are connected with the welt, and I do not broadly claim this as myinvention.

I claim. and desire by Letters Patentfto secure-: I

. As a new article of manufacture, a presse'rfoot made in one piece with two semicircular. grooves or channels, 6 6, arranged parallel throughout the undersurface of the presserfoot, the central fin, f, dividing the channels," 7 and thelateral side projections,mm, extending I 1 1 below thebottorn surface of the central fin, substantially as described.
